We do not support specific compilers, but rather compilers with
reasonable quality of their C++14 support. While developing the
new random generators, I ran into issues with VS2017 where it
rejects perfectly valid C++14 code, **and** the error does not
point me in the right direction to try and work around the issue.
It is time for VS2017 to go.
This commits also adds a script that does the amalgamation of headers
and .cpp files into the distributable version, removes the old
`generateSingleHeader` script, and also adds a very simple compilation
test for the amalgamated distribution.
VS 2017 has an annoying bug, where the result of `__FILE__`
substitution is always lower-cased. This breaks approval tests
and I am not quite convinced that we should fully normalized paths
to accomodate this bug.
We need to remember to undo this in the future though.
Also had to add new project to redirect CTest output, add
separate batch scripts for AppVeyor because it doesn't handle
multi-line batch scripts in yaml properly, and other helper
scripts.
- Added new compilers and OS X images
- Option to run SelfTest under Valgrind
- Merge "Debug" and "Release" configurations into one run
-- This saves apt setup and cmake download step per compiler, 60-90s
- Fix C++14 compilation under Clang 3.8 and up
